The conflicting demand for water, food, and energy is one of the defining challenges of the 21st century. Global Choke Point, a collaboration between Circle of Blue and the Wilson Center, explores the peril and promise of this nexus with frontline reporting, data, and policy expertise.

A quarter of the coal that powers China’s economy is mined in Inner Mongolia, one of the country’s most water-scarce provinces with only slightly under two percent of China’s total water resources. The coal-rich city of Ordos, which produces nearly 70 percent of all the coal in Inner Mongolia, is bookended by expanding deserts—Kubuqi to the north and Maowushu to the south—and may one day run out of water and face a “Day Zero” like Cape Town in South Africa. Both the central and local governments are promoting a number of efforts to create new water supplies in Ordos, such as treating brackish waters and trading water rights. To learn more, the China Energy & Environment Forum recently interviewed Shaofeng Jia, the Deputy Director of Water Resources Research Center at the Chinese Academy of Sciences, who recently completed an extensive study on water-energy confrontations in Inner Mongolia.

From thick smog blanketing the cities, to acid rain corroding soils and ruining crops, air pollution from China’s coal industry is inflicting heavy damage on the country’s environment, its economy, and its citizens’ health. But these clouds of smoke have obscured the less visible (but no less severe) water challenges facing the coal sector and the region it operates in.

This is the first article in a series of case studies of innovative wastewater treatment plants in Brooklyn and Brazil from the China Environment Forum and Circle of Blue’s Choke Point China Initiative, which since 2010 has been exploring challenges and solutions to water-energy-food confrontations in the world’s most populated country.

Chinese cities are being encircled by untreated sludge—a pungent, viscous mixture of human excreta and stormwater runoff. Four years ago in Beijing, trucks loaded with untreated sludge from the city’s largest wastewater treatment plant were illegally dumping mountains of sludge in the outskirts of the capital as “free fertilizer” for peri-urban farms. Similarly, in the southern China city of Guangzhou, disposing toxic sludge into the nearby river required nothing more than a hired boat. From the far western desert city of Urumqi to the eastern metropolis of Shanghai, more and more of China’s cities are struggling to manage mountains of sludge and municipal waste, as well as floods of wastewater and stormwater runoff.

Coal — the reigning king of China’s energy sector — generates 74 percent of the country’s electricity and is the main source of the staggering air pollution blanketing Chinese cities. Prompted in large part by the air pollution problem, the Chinese leadership has begun to pivot away from coal by strengthening monitoring and enforcement to limit coal-fired power plant emissions, piloting CO2 emissions trading projects, accelerating expansion of renewables, and committing to CO2 reductions in the Paris climate agreement.

HONOLULU – Sludge. The final, unwanted byproduct of a toilet flush. The semi-solid stuff that even wastewater treatment plants send packing to the landfill. Unseen in the steel pipes snaking high on the exterior of Honolulu’s H-POWER plant, sludge is injected into a massive boiler where it joins the city’s trash in a roaring inferno. From the gravel lot outside, it all seems very antiseptic and smells less than a stroll past the neighborhood dumpster. But the 70-megawatt waste-to-energy facility is a workhorse, processing as much as 2,000 tons of refuse each day from Oahu’s 1 million residents. All told, it generates up to 10 percent of the electricity needed to power this Pacific island.

The ninth and final story in a series of reports by Circle of Blue and the Wilson Center on the global implications of water, energy, and food challenges in the south Indian state of Tamil Nadu.

MADURAI, India – Before he agreed to serve as minister of state and take command of his country’s mammoth energy production and distribution sector, Piyush Goyal developed one of India’s most spirited political careers. “A man of ideas and competence,” according to First Post, a prominent news organization, Goyal is an accountant and lawyer who rose to the peak of Indian economic and political culture as an investment banker, member of parliament, and treasurer of the ruling Bharatiya Janata Party.

The eighth in a series of reports by Circle of Blue and the Wilson Center on the global implications of water, energy, and food challenges in the south Indian state of Tamil Nadu.

KODAIKANAL, India – In the dogged community of eco-activists, journalists, local leaders, and artists that find common ground defending Tamil Nadu from rapacious development and rampant pollution, Nityanand Jayaraman stands out.

The seventh in a series of reports by Circle of Blue and the Wilson Center on the global implications of water, energy, and food challenges in the south Indian state of Tamil Nadu.

CHENNIMALAI, India – There is river and beach sand aplenty in Tamil Nadu. At 130,000 square kilometers (50,200 square miles), the state is about the same size as Nicaragua and has 95 rivers with sandy bottoms and a long Bay of Bengal shoreline. Or did. For almost all of its thousand-year history, the state of Tamil Nadu took all that sand for granted. No longer.
